第6题
A、Multicast addresses 224.0.0.0 through 224.0.0.255 are always forwarded because they are transmitted with Time to Live （TTL） greater than 1. B、Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routers. C、Multicast addresses 224.0.0.13 and 224.0.0.22 are reserved link-local addresses used by PIMv2 and IGMPv3. D、Because they would map to overlapping IP multicast MAC addresses， multicast addresses 224.0.1.1 and 238.1.1.1 could not be used together. E、Multicast address 224.0.1.1 has been reserved for the Network Time Protocol （NTP） by the IANA F、The administratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar in purpose to RFC 1918 private unicast addresses.

第8题
A、The first 23 bits of the multicast MAC address are 0x01-00-5E. This is a reserved value thatindicates a multicast application B、The last 3 bytes （24 bits） of the multicast MAC address are 0x01-00-5E. This is a reservedvalue that indicates a multicast application C、To calculate the Layer 2 multicast address， the host maps the last 23 bits of the IP address intothe last 24 bits of the MAC address. The high-order bit is set to 0 D、The first 3 bytes （24 bits） of the multicast MAC address are 0x01-00-5E. This is a reservedvalue that indicates a multicast application
